Any special limitations on I2C port bits on sbRIO

[Philbot]

I'm getting to know the new Robotics Starter Kit (uses sbRIO 9631) and I'm looking to add some LEGO Mindstorm sensors to the robot.

These all use I2C serial interfaces.

The example NI I2C FPGA code uses Port Zero bits 0,1,2 &3 to generate two I2C channels.

My question is: Is there anything special about these particular ports or bits?

These default port bits are already being used for encoder inputs on the RSK, so I need to use bits from another port.

Can I just pick any that I'd like, or is there "acceptable" use for certain bits. 

Online docs anywhere that I should consult?

Thanks.

Phil.

Those channels were just chosen for the example. You can use any of the onboard digital lines to perform the I2C communication.
